A DEVICE FOR CONTROLLING A HYDRAULICALLY DRIVEN MOTOR

摘要

The present invention relates to an arrangement for controlling a 5 hydraulically driven motor (2), forming part of a hydraulic system in which hydraulic fluid under pressure forms a main flow through a main duct (1) in which the motor is connected. The motor is adapted to drive a load with varying loading, and one or more valves (6, 7) are adapted for controlling the hydraulic fluid flow through the motor an the one hand during operation and an the other hand for starting and stopping of the motor. One of the valves consists of a flow control valve (7) which is connected in the main duct (1) downstream of the motor (2) and is adapted for an the one hand starting/stopping of the motor and an the other hand constant flow control of the hydraulic fluid flow through the motor.
